Lots of great posts already and I'm late for the discussion.
I'm glad that you broke up with her. Two months in and she needed space for the second time is quite bad.
Now, if you want to be a better man, an alpha male if you'd like to call it, then you must learn from this experience. Don't dodge the pain by trying to forget what had happened. What had happened might be a very valuable lesson in your life. I'll help you to point out what you did wrong, in hopes that you will be much better at this.

Part of why a woman needs space from you is that you were chasing her hard. Before she asked you for a space, did you give her time to miss you?
A woman's deepest desire is to find a man that needs to be conquer agian and again. That man has purpose in life. And it's not centered around her.
If you chased her hard, you were emanating desperation. Desperation is the #1 attraction killer.
If you didn't give her enough time to miss you, you took away mystery from her mind. Mystery is what keeps her want to experience you more.
And lastly (you did this and experienced this), if you do what she told you to do, then you are NOT leading her and she will feel bored by your presence. Do you know why? Because you took away manliness (some might say alphaness) from yourself. By doing what she said, you took away mystery from her mind. What marmel wrote is true. Don't be her dog. You are a man. A man must lead. Leading is a conscious decision. It's hard but it's how your self worth is built. Most men just want to be followers because they don't want to take responsibility for themselves and others. Leading is a habit. You do it everyday in your life.
Next time, don't be too available or too agreeable. If she say, "why don't you do X for me?", you might wanna play hard to get by saying, "I can't. I have other things to do." And if she really wants you to do it, she will do everything she can to change your mind. And this, will lead to more opportunities to do fun things while she persuades you. This is the difference between a boring man and an interesting man.
Women are moved by emotions. Use this for your advantage. I recommend you to stay on this forum. Lots of great people here. You'll learn much more from their advices. And if someday you lean something, don't hesitate to share it with others who still don't grasp it. By teaching others, you strengthen your own beliefs.
Like Spaz wrote to you, it's okay to scream, cry and feel bad about yourself. It's only natural. Give it some time.
When we're studying, we need to keep repeating subjects just to remember them. It's the same thing with a person. If you want to forget about a feeling for her, when the thought came, quickly dismiss it. Do not purposedly trying to reminisce your feelings for her. Remember the experience but dump the feelings.
I see that you are still wanting her to return back to your arms. This is not healthy. What's broken is broken. It will never come back to how it all began. That's why we're all advising you to find another woman. It's easier and more rewarding to start a new relationship than to try to fix a broken one.
